We just moved out to the Dayton area in July, from Seattle. I will say, coming from the west coast to the east coast has been a BIG culture shock. We're adjusting, it's taking a little bit, but it's happening.
We just bought a house in Springboro, and though the area is a little sparse at this time, they're doing a lot of building, particularly in northern Springboro. We looked in Beavercreak, as well as Centerville. Beavercreak is a wonderful area, and is really growing. It had more a west coast feeling to it, if you will. In the end it I didn't want to have a longer commute.
Overall, we've been happy since our move. Housing is substantially cheaper than the west coast, as well as the overall cost of living. People here tend to be more sincere than out west (at least in Seattle). Also, you won't go bored, you're in close proximity to a lot of fun places for the family, as well as a weekend getaway for the grownups.
As far as weather goes...Summer was an adjustment, with the heat and humidity, but you do get air conditioner
(Most people didn't have air conditioners in Seattle). Fall was wonderful. The changing colors and the mild temperatures were great for getting out and enjoying the many fall festivities. Winter has been very mild, we got a little worried when we got several inches of snow in early December, but since then it's been great, very much fall like. We can't wait for spring!
Granted, it's not as glamorous of a place as say Seattle or San Francisco, as mentioned above, however, it is a good place to race a family.
